IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 157,895, dated December15, 1874; application filed September 26, 1874.

To all whom it may concern:

Be it known that I, WILLIAM M. WATSON, of Tonica, in the county of LaSalle and State of Illinois, have invented a new and valuableImprovement in Cultivators; and I do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawing is a representation of a side view of mycultivator. Fig. 2 is a top view, Fig. 3 is a front view, and Fig. 4 isa detail view, of the same.

This invention has relation to improvements on the cultivator for whichLetters Patent were granted to me bearing date on the 9th day of June,1874.; and it consists in mounting the rear parts of the draft-tonguesupon sled-runners, which are secured to the outer sides of thesetongues, and have connected to them, by means of clevises, theshovel-carrying beams, which clevises will allow lateral as well asvertical movements to be given to the beams by the plowman.

In the annexed drawings, A A designate two draft-tongues, which areloosely connected together at their front ends by means of a yoke, B,substantially as described in the schedule annexed to my Letters Patentabove referred tothat is to say, by means of oblong staples a a. C Odesignate shovel-carrying beams,which have secured to them handles G andshovel-standards O 0 To the front portions of these beams O 0singletrees D D are jointed, so that the horses are hitched on the outersides of the tongues, between the sin gle-trees and the yoke. The frontend of each beam 0 is connected to the laterally-extended portion of asled-runner, E, which runner is rigidly secured to a tongue, A, andstrengthened by a brace, b. I use a clevis, F, for attaching each beam 0to its sled-runner, through which clevis a bolt, 0, passes vertically,and bears against the lateral portion of the runner, so as to allow freelateral vibration to the beam. The clevis F is flat and broad, toprevent the beam from tilting laterally, and to allow the beam to bevibrated vertically. I thus allow a universal motion to be given to thetwo shovel-carryin g beams, and sustain them against tilting. Therunners E are angular bars, and they sustain the rear ends of thedraft-tongues A and front ends of the shovel-carrying beams (J. G G aretwo standards, which are rigidly and perpendicularly secured to the rearends of the tongues A. These standards have angular rods 9 9 connectedto them, so as to vibrate freely, and the horizontal portions of therods are connected together by means of clamping-blocks h and a screw,71.

By loosening the blocks h, the shovel-carrying beams can be adjusted atany desired distance apart, according to the height of the corn.

The vertical portions of the rods g 9 being pivoted to the standards,the tongues are allowed free endwise play.

It is important, in connection with my cultivator, mounted on runners E,to employ hooks n n, and to locate these hooks at the rear ends of thetongues, in such positions that they will sustain the beams free fromthe ground when the machine is not in operation.

What I claim as new, and desire to secure by Letters Patent, is-

The tongues A A, jointed together at their forward ends, and capable ofa rearward or forward movement independently of each other, incombination with the runners E E, to the upper horizontal parts of whichare jointed, by the clevis F, the plow-beams O O, by which the latterare capable of a forward or rearward movement with the tongues AA, alateral movement toward or from each other on the horizontal parts ofthe runners, and also a vertical movement on the same, substantially asdescribed.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

WILLIAM MEDD WATSON.
